Special operating modes
The general specifications for the device are detailed in "Ambient conditions during operation
(Page 147)".
In certain circumstances, the Arctic HMI device can be subjected to a higher than the
maximum specified ambient temperature without this affecting the nominal specifications of
the components. These cases are referred to as special operating modes.
The use of these special operating modes is a deviation from the specified intended use of
the device.
Damage to the device
Outside the specified ambient temperature range, the correct function of the device is no
longer guaranteed, not even if the "Temp" LED signals a regular temperature. The device
can be damaged. This can result in machine and system malfunctions and injury.
Outside the specified ambient temperature range, the service life of the device may be less
than that of devices which are always operated at a moderate temperature and humidity.
Operating the device outside the permitted temperature range voids the warranty.
To ensure a long service life and retain warranty cover:
• If the "TEMP" LED comes on red for a high ambient temperature, the device must be
• If the "TEMP" LED comes on red or yellow for a low ambient temperature, the device
• A red or yellow/green flashing "TEMP" LED indicates a very low or high temperature in
Danger of burns
The surface of the device can get hot when the ambient temperature is high. This can
cause injuries and burns. Long skin contact with non-metallic surfaces can cause injury
even at temperatures of 43 °C.
• Monitor the "TEMP" LED. If it is (flashing) red, this may mean the surface temperature of
• Place the device in the wall-mounting bracket and only use it briefly.
• Wear suitable gloves to touch the device.
NOTICE
